Why Doesn't XMLIndex Create and Populate Upon Scale-Up For Eval Table?

Presently working with Oracle release 11.2.0.1 using xmltype securefile binary xml tables.
In a quandry here and hoping not to have to open an Oracle SR...
Able to create a working xmlindex against an 'Acme Eval' table in our development environment against an Acme eval table (estimate ~ 5GB) containing 325,550 rows. Creation takes about 10 mins. No partitioning is being used.
When trying the exact same xmlindex creation against our, much more powerful, pvs platform environment contaning 13,985,124 rows; the xmlindex object shows up as existing in the data dictionary, but the session never stops running after at least 24 hrs of runtime.
The pvs hardware environment uses: (1.) 24 processor, (2.) Solaris-64 OS, (3.) 128GB memory.
Two 1 hr AWR reports for the pvs environment shows a huge amount of logical read/writes. The foreground wait event; 'db file sequential read' dominates the DBTime @ 92%. There is about 4.6 GB physical reads/3.5GB physical writes - not too large relatively speaking. The I/O subsystem is having no problem handling the throughput. The top, by far,Time Model Statistics is the 'sql excute elapsed time' @ 99%. User I/O is the main foreground wait class @92%. These values are similar for both of the AWR report - except one report show the 'CREATE XMLINDEX...' statement as being the top sql. The other report shows ' INSERT INTO CROUTREACH.EVAL_IDX_TAB_I... ' As the top sql.
Been several days since this post. Hoping someone might be able to provide some insight or share their experiences on xmlindexes scaling up to millions of records in the 5 - 10 gb xmltype table range...
Regards,
Rick Blanchard
The frustration here is; there is no obvious database configuration, physical cpu, memory, or I/O issue - other than the logical gets centered around the db file sequential read' wait event.
Can't do much as far as adjusting the create index statement and underlying attendent Oracle xml operations - the main frustration factor here...
The xmlindex is still undergoing record insertions.
Additionally, in the pvs environment; no dml is allowed on the xmlindex and the select statement that works fine using the xmlindex via the optimizer in the development environment doesnt pick up the xmlindex in the pvs environment - as would be expected if the xmlindex wasn't completely populated.
Appears the xmlindex record population is stalled...
In the pvs environment, when performing the dml 'alter index croutreach.eval_xmlindex_ix noparallel';
get this error - typical when an xmlindex is being populated with records:
ALTER INDEX croutreach.eval_xmlindex_ix NOPARALLEL
Error report:
SQL Error: ORA-00054: resource busy and acquire with NOWAIT specified or timeout expired
00054. 00000 - "resource busy and acquire with NOWAIT specified"
*Cause:    Resource interested is busy.
*Action:   Retry if necessary. xmlindex create statement used in both cases is

Create and Populate a Hyperion Planning Cube using Hyperion Data Integratio

Friends,
I am new to Essbase and have worked extensively in Informatica. Hyperion DIM (OEM version of Informatica) is chosen to create and populate a Hyperion Planning System (with Essbase cube in the backend).
I am using Hyperion DIM 9.3.
Can someone let me know (or share a document) how I can do the following
1) Create a Planning application with a Essbase Cube in the backend using Hyperion Data Integration Management
2) How to populate the Essbase outline and the actuals Essbase cube with data using DIM.
Thanks a lot for all help.

Hi,
You cannot create planning applications using DIM.
To load metadata have a look at :- http://www.oracle.com/technology/obe/hyp_fp/DIM_Planning/OBE_Dim_Planning.html
You can refresh planning database in DIM by
To enable the Refresh Database property for a session:
In Workflow Manager, right-click the session and select Edit.
Click the Mapping tab.
Select a Planning target.
Check the Refresh Database box.
Ok?
Cheers

Why Isn't xmlindex being used in slow query on binary xml table eval?

I am running a slow simple query on Oracle database server 11.2.0.1 that is not using an xmlindex. Instead, a full table scan against the eval binary xml table occurs. Here is the query:
select -- /*+ NO_XMLINDEX_REWRITE no_parallel(eval)*/
      defid from eval,
      XMLTable(XMLNAMESPACES(DEFAULT 'http://www.cigna.com/acme/domains/eval/2010/03',
      'http://www.cigna.com/acme/domains/derived/fact/2010/03' AS "ns7"),
      '$doc/eval/derivedFacts/ns7:derivedFact' passing eval.object_value as "doc" columns defid varchar2(100) path 'ns7:defId'
       ) eval_xml
where eval_xml.defid in ('59543','55208'); The predicate is not selective at all - the returned row count is the same as the table row count (325,550 xml documents in the eval table). When different values are used bringing the row count down to ~ 33%, the xmlindex still isn't used - as would be expected in a purely relational nonXML environment.
My question is why would'nt the xmlindex be used in a fast full scan manner versus a full table scan traversing the xml in each eval table document record?
Would a FFS hint be applicable to an xmlindex domain-type index?
Here is the xmlindex definition:

1. In the developemnt environment, no xml source records for defid '52657' or '52599' are being displayed - just an empty output set occurs; in spite of these values being present and stored in the source xml.
This really has me stumped, as can query the eval table to see the actual xml defid vaues '52657' and '52599' exist. Something appears off with the query - which didn't return records even before the corrresponding xml index was created.
2. The query still performs slowly, in spite of using the xmlindex. The execution plan shows a full table scan of eval occurring whether or not a HASH JOIN or MERGE JOIN (gets used in place of the HASH JOIN when the NO_USE_HASH(eval) int is used.
3. Single column 2ndary indexes created respectively for eval_catt and defid are not used in the execution plan - which may be expected upon further consideration.
In the process of running stats at this moment, to see if performance improves....
At this point, really after why item '1.' is occurring?

Creating view to get first row for each table !!

I am having tables(more than 10) which are related using foreign key and primary key relationship.
Example:
Table1:
T1Prim T1Col1 T1Col2
Table2
T2For T2Prim T2Col1 T2Col2 T2Col3
(here T2For will have value same as T1Prim and in my design it has same column name i.e. T1Prim)
Table3
T3For T3Prim T3Col1 T3Col2 T3Col3
(here T3For will have value same as T2Prim)
and so on.
The data in the tables is like For table1 there will be one record, for table2 there will be one record and for table 3 there are more than one records.
Can i view either the first record for each of them or all records from each of them by writing the following view.
I have written a view like this:
Create or replace view test (T1Prim,T1Col1, T1Col2,T2Prim,T2Col1 T2Col2, T2Col3, T3Prim,T3Col1, T3Col2, T3Col3)
As
Select
Table1.T1Prim,
Table1.T1Col1,
Table1.T1Col2,
Table2.T2Prim,
Table2.T2Col1,
Table2.T2Col2,
Table2.T2Col3,
Table3.T3Prim,
Table3.T3Col1,
Table3.T3Col2,
Table3.T3Col3
From
Table1,
Table2,
Table3
where
Table1.Prim = Table2.For
and Table2.Prim = Table3.For
When i ran the select statement on the view I am not getting any data. Whereas there is data when select is ran on individual table.
Can someone please tell me where i am goofing.
Thanks in the anticipation that i will get some hint to solve this.
Eagerly waiting for reply.
Thanks !!

I mean use a collection :
Collection Methods
A collection method is a built-in function or procedure that operates on collections and is called using dot notation. The methods EXISTS, COUNT, LIMIT, FIRST, LAST, PRIOR, NEXT, EXTEND, TRIM, and DELETE help generalize code, make collections easier to use, and make your applications easier to maintain.
EXISTS, COUNT, LIMIT, FIRST, LAST, PRIOR, and NEXT are functions, which appear as part of an expression. EXTEND, TRIM, and DELETE are procedures, which appear as a statement. EXISTS, PRIOR, NEXT, TRIM, EXTEND, and DELETE take integer parameters. EXISTS, PRIOR, NEXT, and DELETE can also take VARCHAR2 parameters for associative arrays with string keys. EXTEND and TRIM cannot be used with index-by tables.
For more information, see "Using Collection Methods".
Syntax
Text description of the illustration collection_method_call.gif
Keyword and Parameter Description
collection_name
This identifies an index-by table, nested table, or varray previously declared within the current scope.
COUNT
COUNT returns the number of elements that a collection currently contains, which is useful because the current size of a collection is not always known. You can use COUNT wherever an integer expression is allowed.
For varrays, COUNT always equals LAST. For nested tables, normally, COUNT equals LAST. But, if you delete elements from the middle of a nested table, COUNT is smaller than LAST.
DELETE
This procedure has three forms. DELETE removes all elements from a collection. DELETE(n) removes the nth element from an index-by table or nested table. If n is null, DELETE(n) does nothing. DELETE(m,n) removes all elements in the range m..n from an index-by table or nested table. If m is larger than n or if m or n is null, DELETE(m,n) does nothing.
EXISTS
EXISTS(n) returns TRUE if the nth element in a collection exists. Otherwise, EXISTS(n) returns FALSE. Mainly, you use EXISTS with DELETE to maintain sparse nested tables. You can also use EXISTS to avoid raising an exception when you reference a nonexistent element. When passed an out-of-range subscript, EXISTS returns FALSE instead of raising SUBSCRIPT_OUTSIDE_LIMIT.
EXTEND
This procedure has three forms. EXTEND appends one null element to a collection. EXTEND(n) appends n null elements to a collection. EXTEND(n,i) appends n copies of the ith element to a collection. EXTEND operates on the internal size of a collection. So, if EXTEND encounters deleted elements, it includes them in its tally. You cannot use EXTEND with index-by tables.
FIRST, LAST
FIRST and LAST return the first and last (smallest and largest) subscript values in a collection. The subscript values are usually integers, but can also be strings for associative arrays. If the collection is empty, FIRST and LAST return NULL. If the collection contains only one element, FIRST and LAST return the same subscript value.
For varrays, FIRST always returns 1 and LAST always equals COUNT. For nested tables, normally, LAST equals COUNT. But, if you delete elements from the middle of a nested table, LAST is larger than COUNT.
index
This is an expression that must yield (or convert implicitly to) an integer in most cases, or a string for an associative array declared with string keys.
LIMIT
For nested tables, which have no maximum size, LIMIT returns NULL. For varrays, LIMIT returns the maximum number of elements that a varray can contain (which you must specify in its type definition).
NEXT, PRIOR
PRIOR(n) returns the subscript that precedes index n in a collection. NEXT(n) returns the subscript that succeeds index n. If n has no predecessor, PRIOR(n) returns NULL. Likewise, if n has no successor, NEXT(n) returns NULL.
TRIM
This procedure has two forms. TRIM removes one element from the end of a collection. TRIM(n) removes n elements from the end of a collection. If n is greater than COUNT, TRIM(n) raises SUBSCRIPT_BEYOND_COUNT. You cannot use TRIM with index-by tables.
TRIM operates on the internal size of a collection. So, if TRIM encounters deleted elements, it includes them in its tally.
Usage Notes
You cannot use collection methods in a SQL statement. If you try, you get a compilation error.
Only EXISTS can be applied to atomically null collections. If you apply another method to such collections, PL/SQL raises COLLECTION_IS_NULL.
You can use PRIOR or NEXT to traverse collections indexed by any series of subscripts. For example, you can use PRIOR or NEXT to traverse a nested table from which some elements have been deleted.
EXTEND operates on the internal size of a collection, which includes deleted elements. You cannot use EXTEND to initialize an atomically null collection. Also, if you impose the NOT NULL constraint on a TABLE or VARRAY type, you cannot apply the first two forms of EXTEND to collections of that type.
If an element to be deleted does not exist, DELETE simply skips it; no exception is raised. Varrays are dense, so you cannot delete their individual elements.
PL/SQL keeps placeholders for deleted elements. So, you can replace a deleted element simply by assigning it a new value. However, PL/SQL does not keep placeholders for trimmed elements.
The amount of memory allocated to a nested table can increase or decrease dynamically. As you delete elements, memory is freed page by page. If you delete the entire table, all the memory is freed.
In general, do not depend on the interaction between TRIM and DELETE. It is better to treat nested tables like fixed-size arrays and use only DELETE, or to treat them like stacks and use only TRIM and EXTEND.
Within a subprogram, a collection parameter assumes the properties of the argument bound to it. So, you can apply methods FIRST, LAST, COUNT, and so on to such parameters. For varray parameters, the value of LIMIT is always derived from the parameter type definition, regardless of the parameter mode.
Examples
In the following example, you use NEXT to traverse a nested table from which some elements have been deleted:
i := courses.FIRST; -- get subscript of first element
WHILE i IS NOT NULL LOOP
-- do something with courses(i)
i := courses.NEXT(i); -- get subscript of next element
END LOOP;
In the following example, PL/SQL executes the assignment statement only if element i exists:
IF courses.EXISTS(i) THEN
courses(i) := new_course;
END IF;
The next example shows that you can use FIRST and LAST to specify the lower and upper bounds of a loop range provided each element in that range exists:
FOR i IN courses.FIRST..courses.LAST LOOP ...
In the following example, you delete elements 2 through 5 from a nested table:
courses.DELETE(2, 5);
In the final example, you use LIMIT to determine if you can add 20 more elements to varray projects:
IF (projects.COUNT + 20) < projects.LIMIT THEN
-- add 20 more elements

Why doesn't my ical and address book no longer sync between the iphone4S and my MacBook?

Can anyone explain why the new iphone doesn't sync back to my MacBook. My ical won't sync, nor will my address book when I make changes to either device? I just bought the phone today and no one at the Mac Store could provide any assistance. I was told that, "it's too new." and had to set up a call with tech support for next Tuesday. I need to work so if anyone could help with this that would be great!
Thank you!

I think my company updated Exchange on Friday and since then I cannot sync with Mac Mail, Entourage does not seem to be working either?
Any fix found

Code to Create and Populate Lookup using Java API

Hi All,
I wish to write a java code to first create a lookup in OIM and then populate with some custom values.
For creating Lookup, I used the following function and it worked:
tcLookupOperationsIntf useLookup=(tcLookupOperationsIntf)factory.getUtility
("Thor.API.Operations.tcLookupOperationsIntf");
useLookup.addLookupCode("Lookup.Custom");
However, If I try using the following function to populate this lookup:
useLookup.addLookupValue("value1","value2",value3",value4");
I got this error:
Thor.API.Exception.tcInvalidLookupException
Please help.
Cheers,
Sunny

You are using the correct API
("value1","value2",value3",value4");
The values which you are providing are wrong.
TRY THIS
addLookupValue("Lokkup.Test", codeValue,decodevalues, "en", "US")
Lookup.Test should be there.

Why doesn't LDAP Priority and Weight change entry in the DNS?

We have two Windows 2008 servers that are Active Directory Domain Controllers. They seem to be configured properly, and are talking to each other.
I want one of the domain controllers to authenticate all of the logins because it's a more powerful box. I want the second DC to take over if the first goes down.
I went into the Registry on the old machine, and created two 32 bit Dword registry keys as follows:
HKLM\SYSTEM\CurrentControlSet\Services\Netlogon\Parameters.
LdapSrvPriority
and
LdapSrvWeight.
Set these to 5 and 150. Assumed the default on the faster server was 0 and 100, thus making the newer server the default choice for logon authentication.
Rebooted server. Checked DNS, and it still is reporting 0 100 for both servers, and doing an
echo %LOGONSERVER% on various workstations seems to show that authentication is roundrobining between both servers.
Why aren't these settings sticking? And why weren't they in the registry when I started?Thanks

Hi,
I tested and DNS record changed as expected.
So please make sure DC you changed point to the DNS that you check. Because there will be some delay before records replicated to another DNS.
You can also check timestamp of the record if it is the latest change.
You can trigger a DNS registration manually:

Why Doesn't -Wait Work, And Why Doesn't Anyone Seem To Care?

I've seen quite a few suggestions bouncing around the internet recommending PowerShell's Get-Content command to provide *nix "tail-like" functionality. The recommended syntax is:
gc <file_name> -Wait -Tail 20
But sadly -Wait doesn't actually seem to do anything--it just sits there blocking and never is updated by the file stream supplied as an argument. Meanwhile, I'm using Cygwin tail and everything works exactly as expected--no sad errors from the OS about
how "so and so already has that file open" no unlimited blocking while staring at 20 minute old log messages.
Does get-content -Wait actually *work* for anyone? If so, what's the magic formula that the PS adepts are using? If not, when is it going to get unbroken?

"If cygwin works so well then why aren't you using it on Windows?"
Well, of course I do use it on Windows. There are times when one has to log into a production box and perform debugging tasks such as inspecting log files on a running system. In that scenario, I'm hardly going to log in and start immediately installing
third-party POSIX environments. :)
While apo32 outlined a trivial test using ping above, the behavior is not limited to ping. You can get the exact same behavior on java application servers logging via log4j. Or .NET applications using log4net. That's great that ping may be replaced by a
.NET equivalent some day. But unfortunately my clients are still going to be making my life miserable by running Tomcat on Windows boxes.
"Even on Unix you cannot tail locked files."
While I've never come across this problem, the case we're talking about here is one where tailing a log file is trivially easy using cygwin and impossible using get-content--in identical circumstances. If that's not what get-content is for, that's
one thing, but if you google "tail in windows" you're inundated with results claiming that get-content with -Tail and -Wait provides the exact same functionality.

Create and Populate Date Dimension for AdventureWorksDW2012

Does anybody have scripts for DimDate for AdventureWorksDW 2012 or 2014?
If I generate Schemas and data, it takes several megabytes. I have requirement that this should be done with script to save space. I have also need to extend the script with local calender requirements.
Kenny_I

If you mean to populate the DimDate table with range of dates, try the following:
Create table #dates (
[date] date not null
declare @d date
set @d ='2010-01-03'; --- change this to the start date that you want
while @d < '2017-01-01' --- change this to the end date that you want
begin
set @d= DATEADD(DAY,1,@d)
insert into #dates (date) values (@d)
end
select date,
[YEAR] = datepart(year, date),
[MONTH No.] = datepart(month, date),
[MONTH] = case datepart(month, date) when 1 then '01 January'
when 2 then '02 February'
when 3 then '03 March'
when 4 then '04 April'
when 5 then '05 May'
when 6 then '06 June'
when 7 then '07 July'
when 8 then '08 August'
when 9 then '09 September'
when 10 then '10 October'
when 11 then '11 November'
when 12 then '12 December'
end,
[day]= datepart( day, date),
[weekday] = case datepart(weekday, date) when 1 then 'Sunday'
when 2 then 'Monday'
when 3 then 'Tuesday'
when 4 then 'Wednesday'
when 5 then 'Thursday'
when 6 then 'Friday'
when 7 then 'Saturday'
end

Why doesn't the artist and album name show up on my iPod?

I edit each of my song through "Get Info", so I just simply type in the artist and album name. When I eject my iPod, the artist and album name doesn't show. Solution?

That happened to me too... It's a glitch... what I did is press sync right when i put my ipod in.. sometimes it doesn't work... just do it some other time again...or change someting in the song (getting info) It appears randomly...
